Perhaps a better understanding of the effect of the tree would help in understanding its meaning.

Traditionally, it is thought that Adam and his spouse expressed shame to be seen naked. This interpretation doesn’t make logical sense because The Creator knows “the creation”. In other words, the God created them and knows what they look like naked.

I believe that it is not shame of nakedness but the surprise of seeing their “physical” selves that prompted them to try to cover themselves.

This may confirm that humans have a dual nature, “physical” and “hidden/spiritual”.

In this world, the “physical” side is apparent while the “spiritual” side is hidden from us.

Perhaps in heaven, it was the other way around, until eating from the tree made the “physical” side apparent to Adam and his spouse.
